ATOI(3)			   BSD Programmer's Manual		       ATOI(3)

NAME
     atoi - convert ASCII string to integer

SYNOPSIS
     #include <stdlib.h>

     int
     atoi(const char *nptr);

DESCRIPTION
     The atoi() function converts the initial portion of the string pointed to
     by nptr to integer representation.

     It is equivalent to:

	   (int)strtol(nptr, (char **)NULL, 10);

SEE ALSO
     atof(3), atol(3), strtod(3), strtol(3), strtonum(3), strtoul(3)

STANDARDS
     The atoi() function conforms to ANSI X3.159-1989 ("ANSI C").

CAVEATS
     atoi does no overflow checking, handles unsigned numbers poorly, and han-
     dles strings containing trailing extra characters (like "123abc") poorly.
     Careful use of strtol(3) and strtoul(3) can alleviate these problems, but
     strtonum(3) can be used to convert numbers from strings much more safely
     and easily.
